A psychologist notices their biofeedback system is producing inconsistent electromyography (EMG) readings across sessions. What is the FIRST corrective step?
Answer: Check and clean electrode connections and sensor placement sites
Inconsistent EMG readings most commonly result from poor electrode-skin contact, so inspecting and cleaning connections is the first diagnostic step before considering hardware replacement.
Under HIPAA, when decommissioning a computer used for psychological testing, which step is MANDATORY before disposal?
Answer: Perform a certified data wipe or physical destruction of the storage drive
HIPAA requires that PHI stored on electronic media be rendered irrecoverable through certified wiping or physical destruction before disposal.
A telehealth platform used for therapy sessions shows a 2-second audio delay. Which factor is MOST likely causing this latency?
Answer: Insufficient network bandwidth or high packet loss
Audio latency in video conferencing is predominantly caused by insufficient bandwidth or network congestion rather than hardware or certificate issues.
When conducting neurofeedback therapy, a technician observes 60 Hz electrical noise contaminating the EEG signal. What is the BEST intervention?
Answer: Apply a notch filter at 60 Hz and check for grounding issues
60 Hz artifact is electromagnetic interference from power lines and is best addressed with a notch filter combined with proper equipment grounding.
A psychologist using a computerized cognitive assessment battery notices the touchscreen is not registering responses accurately. After restarting fails to resolve the issue, what should be done next?
Answer: Perform touchscreen calibration using the device's built-in utility
Touchscreen calibration through the device's built-in utility corrects misalignment between touch input and display coordinates before escalating to hardware replacement.
Which maintenance practice BEST prevents data loss from a psychological testing workstation during a power outage?
Answer: Using an uninterruptible power supply (UPS) with automatic voltage regulation
A UPS provides immediate battery backup and voltage regulation, protecting both the hardware and any in-progress assessment data during a power outage.
A portable galvanic skin response (GSR) device used in anxiety assessments shows baseline drift over the course of a session. What is the MOST likely cause?
Answer: Temperature-related changes in electrode gel conductivity
GSR baseline drift is commonly caused by temperature changes affecting electrode gel conductivity and the electrochemical interface at the skin.
